Abstract

Scheinwerfer für Fahrzeuge mit einem eine Lichtscheibe aufweisenden Gehäuse (7), in dessen Innenraum (3) mindestens ein Lichtmodul und ein Lichtleitelement (6) mit einer Lichtaustrittsfläche (5) angeordnet ist. Eine Lichtquelle (1), die eine LED ist, ist einer Lichteinkoppelfläche des Lichtleitelements (6) zugeordnet und im äußeren Randbereich des Gehäuses (7) angeordnet. Zwischen der LED (1) und dem Lichtmodul verläuft ein als Wärmesperre dienendes erstes Wandelement (8) einer die LED (1) aufnehmenden Kammer (2).
